The EU directive in brief

The directive basically deals with two types of noise induced hearing damages: Acoustic shock and excessive noise exposure throughout a working day

Protection against acoustic shock

Acoustic shocks can cause temporary or permanent traumatic damage to hearing. The directive sets a limit to these types of sudden loud sounds at 135dB(A) which is comparable to standing next to an airplane taking off.

Protection against excessive noise

The directive defines two critical levels for noise exposure throughout a working day. For up to 80dB(A) the employer has no obligations. Between 80dB(A) and 85dB(A) the employer should offer hearing protection and education. For levels exceeding 85dB the employees must be provided with and wear hearing protective equipment.
